The management of medically unexplained symptoms.

Medically unexplained symptoms occur in up to 50% of new medical out-patients. Health care seeking may not be related to the presence of physical disease but may reflect social problems, psychological disturbance, or frank psychiatric disorder. Management of unexplained physical symptoms depends on the duration of symptoms. If acute, exclusion of physical disease, as well as providing symptomatic care, is a priority. The patient's fears of illness need to be addressed and an explanation in simple terms of the symptoms provided. Adverse life situations should be identified and, where possible, rectified. Psychiatric disorders require appropriate treatment. When symptoms are chronic, conservative management is required to contain the symptoms and avoid iatrogenic problems.
